ARTIFICIAL-GAS BURNER Specification of Letters Patent.

Patented Mar. 14:, 1911'.

Application filed January 17,. 1910. Serial No. 538,379.

To all whom it 'uw-y concern:

Be it known that l, Jaeon \Vnm'rz, a citizen of the inted States, and a resident of of Ohio, have invented a new and useful 'll'nprovement in Artificiaht-ias Burners, of

wlnch the follownig is a specification, the

principle of the invention being herein explained and the best mode in which I have eonteniplattal applying thatprinciple, so as to distinguish it from other inventions.

i The present invention relates to gas burners, and has more particular relation to a burner designed for the purpose of burning artificial gas.

In the burning of artificial gas, as compared with natural gas, it is important that the amount of air fed to the mixture in order to effect complete combustion shall be capable of considerable variation. Owing to various conditions, the amount of air so fed, if constant and unvariable, will notat all times produce an effective combustion,

and it is the general object of the present invention to provide a burner for use with artificial gas which is adapted to provide a reguhible auxiliary air supply.

The annexed drawing and-the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing :Fi gure 1 is a vertical section of a burner embodying my invention; F ig. 2 is a vertical section on the line 2-2 in Fig. 1; andd ig. 3 is a vertical section on the line 33 in Fig. 1.

The burner comprises primarily a metal -asing A which is formed at one end with an outwardly extending flange a. The casing A is integrally formed with two concentric tubes a and. o extending therethrough. The outer tube a is longitudinally divided by partitions a so as to provide a plurality of longitudinal passages a, which passages open at the inner end of the burner into the passage provided by tube a, while at.

their outer ends they open into the atmosphere through the flange a. A plate B is mounted cxteriorly against the flange a and is secured thereto by screws b, which screws engage the outer edge of the plate B so as to allow rotation thereof, and H to plate is ends of which engage one of the screws 1) and serve to limit rotation of the plate. Cleveland, county of Guyahoga, and State and hence to close the outer ends of suchpassages. An air supply! piperG exteriorly oi the casing is connected with the tube a by a suitable coupling. A gas tube d ex teluls-centrally through the casing concentrio with tubes a and a and exteriorly of the casing is connected with a gas supply pipe D.

From this brief description the operation of my burner will be obvious and its advantages apparent.

tive tubes combine at the common orifice E thereof to form a resultant combu'stlble mix- The supply of gas and air admitted to the burner through the respeo-- t-ure.. If, under varied conditions, it is found that more or less air is desired to produce a mixture of the required efliciency, the

supply of such additional air may be regulated by rotation of the plate B so that the apertures therein will be put into, or out of,

register with the longitudinal passages of the outer tube, and thus will allow or prohibit the passage of air through the outer longitudinal passages. By means of this readily accessible regulator, then, the exact amount of air desired'to be mixed with the gas in order to form a mixture of the required efficiency may controlled.

Other modes of applying the principle of.

myf-invention may be employed instead of the" one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of Such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. A gas burner, comprising three concentric tubes having a common orifice, a gas supply pipe connected with one of the tubes, an airsupply pipe connected with another --'t the tubes, the third tube being divided into a plurality of longitudinal passages' be quickly and easily coinnIunicating. at their oluter ends with the zitn'iospherc, and means for coi'itrolling such coinnnmieution.

2. A. gas burner, comprising three eonecntric-tul'ies having at common orifice, a gas supply pipe connected with the inner tube, on air supply pipe connected with the intermediate tube, the outer tube being divided into it plurality of longitudinal passages eonnnumeuting at their outer ends with the atn'iosphere, and means for controlling such communicution.

3. A gas l'mrner, comprising three concentric tubes having a common orifice, a gas supply pipe connected with the-inner tube,

an air supply pipe connected with the intermediate tube, the outer tube being divided into a plurality of ll'mgitudinul passages having openings at their outer ends into the utn'iosphere, and a plate rotatable in a plane transverse to the axis 01'' the tubes, the plate being provir'led with apertures adapted to register with said openings,
